Anyone know of a good instructional video on how to do this? Or has anyone had a shop do a coilover install on a g20 and have a ballpark on how much I should expect to pay?

I was charged $600 for initial install and then $400 for subsequent installs there after since I switch between coilovers for track use and then back to lowering spring for daily use. I also have an excellent relationship with my Indy shop so that plays a role.

10 posts down is a DIY spring install post with some links that should have all the info you need. I did my spring/strut install myself and highly recommend doing it yourself if you have the space/time!

Here's a video from Kies for lowering springs install on an M340i, it's what I used as I'm in the process of installing a set of Ohlins R&T on my car. One thing to consider, you will need some specialty tools, spring compressor of course but some strut nut sockets as well. In retrospect, I'd probably just rent or buy a set of pass through sockets but I'm not sure if you'd be able to torque some nuts correctly with that. Otherwise, I needed a 16mm (sway bar end links), 18mm (OEM strut nut), 17mm, and could have used a 14mm if it existed. The 17 and 14 are specific to the nuts provided by Ohlins so YMMV.

There's also a thread on Page 2 for Ohlins install that I found helpful for other resources too
